Question

how does smell of food being cooked spread so fast? ​

Answer 1

The smell of food being cooked spread fast because of Diffusion.  

• Kinetic Energy is produced while cooking .
• Because there is a rapid temperature increase, the Kinetic Energy also increases thus resulting in the matter particles to move rapidly by the diffusion process.
• When these air particles mixes in air it touches our nose resulting us smelling the aroma or flavours of the food.

Answer 2

Explanation:

The smell of food being cooked spreads very fast because of the kinetic energy produced. whenever there is an increase in temperature the kinetic energy also increases causing the particles of matter to move fastly by the process of diffusion
